Title:

ROTARY ELECTRIC MACHINE

Document Type and Number:

Japanese Patent JP2016101064

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a rotary electric machine that is able to improve dynamic balance with fewer steps.SOLUTION: The vector Z of centrifugal force opposite to the resultant vector Y of centrifugal force acting on each slip ring bus bar 12u, 12v, 12w on a plane surface perpendicular to the direction of rotation axial line X when an inner rotor 1 is rotating with respect to a rotation axis X is generated. Accordingly, dynamic balance of the inner rotor 1 can be obtained. An object serving as a weight is disposed on a line along which the direction of the resultant vector Y is rotated 180 degrees around the rotating axis X. Accordingly, the vector Z of centrifugal force reverse to the resultant vector Y is generated, and the resultant vector Y and vector Z are balanced. Accordingly, dynamic balance during rotation of the inner rotor 1 with the slip ring bus bars 12u, 12v, 12w and slip rings 15u, 15v, 15w attached thereto can be improved.SELECTED DRAWING: Figure 4
